HOLLOW WHEEL-RIM.

SPECIFICATION forming part of Letters Patent No. 446,189, dated February10, 1891.

Application filed December 24,1889. Serial No. 334,855. (No model.)

To all whom, it may concern:

Beit known that I, ALBERT H. OVERMAN, of Springfield, in the county ofHampden and State of Massachusetts, have invented a new Improvement inIlollow \Vheel Rims; and I do hereby declare the following, when takenin connection with accompanying drawing and the letters of referencemarked thereon, to be a full, clear, and exact description of the same,and which said drawing constitutes part of this specification, andrepresents in the fign re a View in transverse section of one form whicha wheel-rim embodying my inyention may assume. My invention relates toan improvement in hollow rims for velocipede-wheels. the object being toproduce a simple and stiff rim from a single piece of sheet metal.

IVith these ends in view my invention consists in a hollow wheel-rimformed from a single piece of sheet metal and having its body portionand its bed each containing one of the edges thereof, the said edgesbeing shaped to be united below the edgeof one edge of the rim.

My invention further consists in certain details of construction, aswill be hereinafter described, and pointed out'in the claims.

Under myinvention enough metal is taken 0 in at one edge of thesheetanetal strip or blank to form the bed H, which therefore forms acontinuation of the body portion B of the rim and contains one edge ofthe strip. As shown in the drawing, the other edge of the strip is bentinward and downward and shaped to form a shoulder C and a seat I), thelatter supporting'the edge of the bed and the former preventing the samefrom outward displacement when resting upon said seat. The edges of themetal arethus united 40 at a point below the edge of one edge of therim.

In carrying out my invention the edges of the metal may be united oneither the inside of the rim or on the outside thereof, and it isapparent that the edges of the metal may be bent in a variety of Ways insecuring them together. I would therefore have it understood that I'donot limit myself to the exact construction shown and described, but holdmyself at liberty to make such changes and a1: terations as fairly fallwithin the spirit and scope of my invention Having fully described myinvention, what I claim as new, and desire to secure by Letters Patent,is

1. A hollow wheel-rim formed from a single piece of sheet metal andhaving its body portion and its bed each containing one of the edgesthereof, the said edges being shaped to be united below the edge of oneedge of the rim, substantially as described.

2. A hollow wheel-rim formed from a single piece of sheet metal andhaving its body portion and its bed each containing one of the edgesthereof, the edge in the body portion being shaped to form a seatlocated below the edge of one edge of the rim for the edge contained inthe tread to rest upon, substantially as described.

ALBERT I-I. OVERMAN.
